CONDENSED MILK.
fasw it In Prspared.--An Interest-
Ing Process.

NJ. Louis Grandeau has just published
a succiaes and instructive account Of
dairy farming in Switzerland. There are,
he tells us, about los, 900 head Of cattle
in Switzerland, rather more than half Of
which are cp.s. The total quantity Of
milk which they yield in course OF year
Is 223 )0,0JJ gallons, the daily average
per cos being one and ono.quarter gal.
long, and the value vi this milk, estimated
In English money at about six pence per
gallon, is about 1915 600 pounds sterling.
NJ. Grandeau then proceeds to show how
this large quantity Of milk Is disposed OF.
In the first place one-half 10 used in
making A., 900 tons Of cheese. and Of this
quantity IS per cent. is thin cheese-that
IL to say, made with skim milk. The
cream taken from the milk used in max
ing thin cheese goes TO make Is 900 tons
Of butter, which is not qnite enough for
home consumption. Bat Of cheese some
thing like 800, 600 pounds sterling worth
is exported every year. The native con-
sumption Of milk itself, and the prepare
ton Of condensed milk, accounts for an
other 80, 900 900 gallono, this amounting,
with what is converted into butter and
cheese, TO SO per cent. OF the whole. The
remaining ii per cent. goes toward rear
ing the 800, 900 calves which are, taking
one year with another, TO be found In
Switzerland. NJ. Grandeau then goes on
to describe the operations OF the Con-
densed Milk Company, which, with its
capital OF 100000 pounds sterling, has
seven factories, of which three Cham,
Guin and ReichenbachtJ are in switzer-
land.
This industry had its origin, SO far as
Switzerland was concerned, at Cham,
where, in 1866, Mr.. Page, the United
States Consul at Zurich. determined to
try an experiment which had been con-
Quoted successfully upon large scale in
his own country. He had great difficulty
in getting any one to believe in the pos
sibility Of success, and for the first year
or two his factory did not condense the
milk Of more than 800 COWS, or make
more than 10000 pound-tins Of con-
dehsed milk. At the present time the
Chain factory receives the milk OF 5000
COWS, and turns out more than IL, ,000, 900
tins Of milk year.
The milk is brought 10 the factory OH
large trolleys, each holding eighty cans; !;
the company itself fetching the milk from
the various farms, and giving uniform
price Of 5R pence per gallon for 1t. Upon
arriving at the factory the milk is passed
into a large reservoir through net which
acts as q strainer. This reservoir also
serves as one Of the scales Of q machine
which weighs the milk. After the milk
has been weighed Q plug is Withdrawn
from the bottom Of the reservoir, and the
milk runs out into large boilers Of copper,
where it is mixed with sugar Of the same
weight as itself. When the sugar Is dis.
solved theliquid mixture runs into vacuum
boilers, where it undergoes, at very
high temperature, the process of conden.
sation. In the course Of three hours II
il reduced to about third Of it's original
volume by the elimination Of water,
while the essential elements OF the milk,
such az lat and caseine, are in no way
affected. From the condensing boilers
the liquid mixture, which has about the
same consistency as fluid syrup, ia
passed into large cylinders which are con-
stantly being immersed in cold water.
where it rapidly cools. The condensed
milk, when cold, is raised by machinery
into the workshops, where it is put into
metal tins, which are Immediately sealed
Theoretically, and are then ready for sale.
All the cans used for bringing in the
milk are first washed out with water,
then scrubbed inside and finally steamed,
before going back TO the dairy.
The treatment Of this large quantity OF
milk, and the fabrication and filling oi
some $4,000 tins per diem, would be i'm.
possible unless the greater part Of tho
work was done by machinery and, from
the cutting out Of the sheets Of metal
which are used for making the tins, to the
fastening down of the wooden cases in
which the milk is sent all over the world
all is done by machinery, single work
man being able TO solder 400 tins ar
hour, thanks TO the excellence Of the
machines Inc manages.-Chicago Times
